What techniques are used to enhance ResNet-50's object recognition?

ResNet-50, a popular deep learning model for object recognition, employs several techniques to enhance its performance. One key technique is the use of residual connections, which help overcome the degradation problem by allowing gradients to propagate more easily through the network. These connections skip a few layers and add the input of a previous layer to the output of the current layer, facilitating information flow and preventing loss of learned features. Another technique used is the bottleneck architecture, where 1x1 convolutions are used to reduce the number of input channels before applying 3x3 convolutions. This helps reduce computation without significant loss of accuracy. Additionally, ResNet-50 utilizes skip connections from multiple layers to the final classifier, allowing for the combination of both low-level and high-level features, leading to better object recognition performance. These techniques collectively contribute to the enhanced object recognition capabilities of ResNet-50.
